. satinata-ritmes ,smal-Naavina To all whom Maag/concern i n -Be `it known thatLL BENJAMINQDAnn, or

Minneapolis, Hennepin icaunty, Miilr'hajsata., f .have invented certain new ,anduseful 11n-v provements in Wheel-Rims, of which 'the following is a specification.

My invention relates to wheel runs ,de-

signed particularly for 4use -with punctnreless tires, or those wherein a yielding gfiller of the sections. 1

is employed tube.

The object of the invention is to prOVldea simple, inexpensive devic'gl by .rneans of which the opposing'annular sectlons of the rim canbe easily and quicklylocked together.

My invention consists generally 1n a rim in place of'- the usual pneumatic composed of annular sections having abut.

ting edges, and 'a loose band locking said abutting 'edges together. v

'In the accompanying drawings forming part of this specification, Figure is atransverse sectional view showingthe rim sections in .their locking.l position, Fig. 2 is a 'similar' view, before the sections are'drawn together to compress the filler, `Fig. 3 is a detail view, illustrating the application of the locking vmeans to therim sections, Fig. l is a detail sectional View, showing the preferred means for disengaging the locking band from its locking position.

In the drawing, 2 represents Va felly provided with clips 3 and 4 secured to the felly by a bolt 5. p i 4 6 is theouter casing and 7 the filler.

8 and 9 are the rim sections, having outer edges adapted to engage the lipsofthe casing. The inner abutting edges of said sections have lips 10 and 11 kformed thereon which' bear upon one another when the sections are squeezed together by the application of a suitable clamp to the otherV portions For the purpose of locking the Irim sections together when the flllerhas been compressed, I provide a series of plates 12, each having longitudinalslots 13 to receive pins on the rimsec-tions .9. These slots and pins allow a limited longitudinal movement of the plates. The plates are provided on one side with lateral .extensions 15 having recesses 16 therein which are adapted to receive the lugs l0 and 1v1 when the plates are moved lengthwise in 'one direction, thereby holding the rim sections securely in their locking position.
